T0 all whomz't may concern.'

Be it known that I, PETER' BEGHnI-TI, a citizen of the United States, residing at the cityand county of San Francisco and State of California, have invented new and useful Improvements in Wire Tighteners and Twisters, of which the following is a speciication.V

-This invention relates to tighteners and twisters for wires such as are used for tying forms together in the construction of concrete walls andthe like.

In a prior application filed by me September 10, 1924, Serial Number 736,952, now Patent No. 1,543,491 I show a clamp and tightener for similar purposes, and in the present invention I have modified the device so that the wires can be more conveniently tightened and thereafter twisted, thus making it possible to immediately remove the tightener for use elsewhere.v

One form which my invention may vassume is exemplified in the following description and illustrated inthe accompanying drawing, in which Fig. 1 shows a perspective view of a set l of forms, showing my device applied to the tie wires, in position for tightening vthe same;

Figure 2 shows a similar view with the device of the presentinvention in position for twisting the wires;

Fig. 3 shows an end elevation ofthe device;

Fig. 4 shows a plan view of the same;

Fig. 5 shows a side elevation.V

In its present form the ltightener and twister comprises a tapered or wedge-like plate 10 having a heel portion 11 extending at right angles thereto on the widened end. Fitted slidably upon this tapered or wedgelike plate is a clamping loop or band 12. At the narrow end of the plate 10 is an opening to slidably receive a rod or bar 13.

The device may be used in connection with forms such as indicated at 14, which are tied together by looped wires 15.

In the operation of the devlce, the endsof the tie-wires are passed between the loop 12 and the plate 10, the said vloop being retracted so as toA permit the wires to be easily inserted therein. The device is placed agiinst the form with ythe heel` portion 11 resting against a rigid portion of the form, and the clamping loop 12 is moved forwardly or towards the widened'end'ofithe plate 10, soas to engage the wire-ends. The

f operator then pulls outwardly on the rod 13 as indicated in Fig. 1, which will cause the clamping loop 12 to tightly engage the wires, and the said clamping loop rand plate 10 will be pried outwardly with the end of the heel portion 11 acting as a fulcrum. When the wire is suiiciently tightened (which may require one or more operations of the device) the said device is then rotated so as to twist the wire ends as indicated iny Fig. 2.- After lthewire ends are sufficiently twisted, the device can be removed and other wires tightened and twistel in a similar manner.

The rod 13 may be arranged in any desired manner upon the plate 10, but it is preferable to have it slidably mounted thereon and provided with enlarged ends 16, so

as to prevent removal or loss of the parts.

By so slidably mounting the rod it can be shifted endwise -to clearv any obstructions that ymay be inthe way of the operator.

Various changes in the construction and arrangement of the several parts herein shown and describedmay be employed without departing from thel spirit of my invention, as disclosed in the appended claims.

What I claim as new and desire to secure by Letters Patent is: 1. The combination with a form for concrete walls of` the characterindicated, and looped wires for aligning the forms and y preventing spreading thereof, of a wedgelike plate having a heel portion formed at one end thereof torest against the form, a clamping member slidably mounted Von the wedge-like plate to engage the ends of the looped wire, and means in connection with said wedge-like plate for prying they same outwardly, with the heelportion as a fulcrum, said means also enabling the operator ytoturn the plate whereby to twist the ends of the wire.

2. The combination with a form for concrete walls of the character indicated, and a looped wire for aligning the forms and preventing spreading thereof, of a wedgelike plate having a heel portion formed at the enlarged end thereof and extending at right angles thereto, and adapted to rest `against the form, a clamping member slidably mounted on the wedge-like plate to engage theends of the wire, and a rod slidably mounted on the outer end of said plate, forming a lever whereby the plate may be pried outwally withthehel Sasfza fulcruin, so as to tighten the wire and may "likewise be turned so as to twist the wire after the sanne is tightened.

3. A tightener and twister for the Apurpose stated, comprising a Wedgelikep-late, a clamping ring sliclable on the plate, a heel portion on the widened end of "the plfate,land means on the opposite end of the plate forming a lever whereby to tilt the plate or turn the same.

4..,Atightenerf'ancl twister orthe purpose stated, comprising a wedge-like'plate, a clamping ring slidable on the plate, a heel :portion Lonfthe widenedeend of the plate,

and a rod slidably mounted on the oppositev -endof the plate, forming a lever for tilting the plate or turning the saine.
